Natural fiber–based composite is an emerging research area due to its significant advantages over synthetic fiber–based composite. The present research aims at analyzing the influence of abaca fiber reinforced polyester composite on the dynamic mechanical analysis (DMA). Additionally, pH of zero point charge has been determined for pure matrix, untreated, and treated specimen. In abaca fiber-based composite system, the composition of fiber is varied from 10 to 40 wt%. To enhance the physical interaction between the fiber and the matrix, the abaca fibers of 4, 6, 8, and 10 vol% are subjected to NaOH treatment. It is surface treated using NaOH. The enhancement of the bonding between the matrix and treated abaca fiber has been ensured by FTIR test. The voids, matrix crack, and microspore presence in the abaca-based composite specimen during fracture test has been examined by scanning electron microscopic image. An increase of dynamic mechanical properties is observed in the following order: pure matrix, abaca fiber reinforced polymer composites, and chemically treated abaca fiber reinforced polyester composites. DMA of chemically treated abaca reinforced polyester composite has enhanced due to the removal of hemicelluloses and lignin from the surface of the fiber, which indeed creates micropores and rougher morphology on the fiber surface.

天然纤维基复合材料是一个新兴的研究领域，因为它比合成纤维基复合材料具有显着优势。本研究旨在分析蕉麻纤维增强聚酯复合材料对动态力学分析（DMA）的影响。此外，还确定了纯基质、未处理和处理样品的零点电荷 pH 值。在蕉麻纤维基复合材料系统中，纤维的组成从 10% 到 40% 不等。为了增强纤维与基体之间的物理相互作用，4、6、8 和 10 vol% 的蕉麻纤维经过 NaOH 处理。它使用NaOH进行表面处理。FTIR 测试确保了基质和处理后的蕉麻纤维之间的结合增强。空隙、基体裂纹、通过扫描电子显微镜图像检查了断裂试验期间蕉麻基复合材料试样中存在的小孢子和小孢子。按以下顺序观察到动态机械性能的增加：纯基体、蕉麻纤维增强聚合物复合材料和化学处理的蕉麻纤维增强聚酯复合材料。由于去除了纤维表面的半纤维素和木质素，化学处理的蕉麻增强聚酯复合材料的 DMA 得到了增强，这确实在纤维表面产生了微孔和更粗糙的形态。
